Astrophysicist Jackie Faherty is blogging about the upcoming transit of Venus, which will take place next week. In her first post, she explains what the transit is, when it occurs, where she will be observing it—and where New Yorkers can catch a glimpse of the phenomenon.

A rare astronomical event is upon us: our sister planet Venus is about to transit our Sun. Depending on your geographic location, this means that the distant planet will glide across the face of the Sun appearing as a small black dot for several hours. Just like the Moon will sometimes pass between the Earth and the Sun, causing a solar eclipse, so do the innermost planets Venus and Mercury. However, since Venus and Mercury are many times more distant to us than the Moon, and since their orbits are not perfectly aligned with that of the Earth, transits of the inner planets are far more rare than solar eclipses and the shadows they cast are smaller. But the event is no less dramatic and unfolds over several hours rather than mere minutes.

In the first Ph.D. defense held by the Richard Gilder Graduate School, Sebastian Kvist today successfully defended his dissertation about blood-feeding leeches, paving the way for him to receive his doctoral degree from the Museum.

Over the next two weeks, a team from Science Bulletins, the Museum’s multimedia online and exhibition program, will visit Peru to film a short documentary about protecting potato biodiversity in the region. Producer Tania Van Bergen, who is traveling to Lima and to the Huancavelica region, will be sending photos and dispatches from her trip in the coming weeks.

A web-based application that tracks dangerous viruses as they spread has been restructured to allow even wider use of the program around the world. SUPRAMAP, a program that synthesizes large, diverse datasets to help researchers understand the evolution of infectious diseases across hosts and geography, was developed in 2007 by the Museum, The Ohio State University, and the Ohio Superconductor Center. In a recent paper in the journal Cladistics, researchers from these institutions describe how they reconfigured SUPRAMAP’s server to let researchers and public safety officials develop their own applications for the program.

In the late 1960s, Curator Emeritus Niles Eldredge was a graduate student with a passion for trilobite eyes. He had been taught to expect slow and steady change between the specimens of these Devonian arthropods he collected for his dissertation. Only his trilobites were doing one of two things: staying the same, or evolving in leaps.
